XSCF Overview

This chapter provides an overview of the system monitoring and control facility
(eXtended System Control Facility, or XSCF).
1.1

XSCF Features

The XSCF firmware (Note 1) is a system monitoring and control facility consisting of
a dedicated processor that is independent from the system processor. While input
power is supplied to the server, the XSCF constantly monitors the server even if no
domain is active. The XSCF provides an interface between the user and the server.
The XSCF uses different functions to achieve high system availability. The XSCF
firmware is a single centralized point for the management of hardware
configuration, control of hardware monitoring, cooling system (fan units), domain
status monitoring, power on and power off of peripheral devices (Note 2), and error
monitoring. The XSCF centrally controls and monitors the server. The XSCF also has
a partitioning function to configure and control domains, and it has a function to
monitor the server through an Ethernet connection so that the user can control the
server remotely. Another function is to report failure information to the system
administrator and a remote control input/output function.
Note – (1) XSCF is the firmware running on the Service Processor in the server. In
the rest of this chapter, although XSCF firmware programs are called XSCF
firmware, or XSCF, they all have the same meaning. The board with the installed
XSCF firmware is called the XSCFU (also referred to as the "XSCF Unit") or Service
Processor. Processors on server boards are called CPUs.
